Definitions

  • This invention relates to the field of control circuits for food preparation machines. More specifically, it relates to a slice control circuit for slicing machines of the type commonly employed for producing prepackaged sliced bacon or cheese.
  • Such machines include a conveyor system on which the product to be sliced is placed.
  • a rotating blade is positioned transversely on the conveyor system in a manner so that the product is sliced as the conveyor moves the product towards the blade. Because the product is moving forward during the slicing there is a pronounced tendency for the slices to be offset from the vertical (FIG. 5) and this creates several problems.
  • Another object of the invention is to provide a slice control circuit for a slicing machine which will maintain the conveyor speed in proper relationship with blade velocity during slicing.
  • a further object of the invention is to provide a control circuit for a slicing machine including switchable means whereby initial positioning of the product can be accomplished at a first rate while subsequent slicing operations are accomplished at a second, slower rate.
  • FIG. 1 is a simplified schematic of a slicing machine suitable for use with the present invention.
  • FIG. 2 is a side elevational view of the slicer blade employed in the machine of FIG. 1.
  • FIG. 3 is a schematic diagram of the slicer control circuit according to the present invention.
  • FIG. 4 is a waveform diagram useful in understanding the operation of the circuit of FIG. 3.
  • FIG. 5 is a schematic representation of a slab of product, such as bacon or cheese, which is to be sliced.
  • FIG. 1 a simplified view of slicing machine 10 suitable for use with the present invention is shown.
  • the essential features of the machine are a conveyor system 11 upon which the unsliced product 12 is placed.
  • the conveyor system is driven by a reversible motor (not shown), the speed and direction of which are controlled in a manner to be described.
  • the conveyor system moves the meat 12 into the proximity of a rotating slicing blade 16.
  • FIG. 2 A typical blade for use in a slicer of this type is illustrated in FIG. 2.
  • a blade includes a spirally curved portion which slices a predetermined amount of product off of the leading end of the product as the latter travels past the blade.
  • the slicing begins at approximately the point 20 and ends at 23 each time that the spiral portion of the blade rotates past the product.
  • the sliced product drops onto a table or second conveyor system (not shown).
  • Operation of the slicing machine continues in this manner until the product has been exhausted or, as is more frequently the case, a desired amount of product has been sliced. At that point slicing is interrupted in order to permit the sliced product to be weighed and/or moved to subsequent processing stations for packaging, etc.
  • the conveyor 11 is desirably reversed to remove the product from the slicing blade to avoid generating partial or nonuniform slices.
  • the conveyor again moves the product towards the slicing blade.
  • the slicer control circuit be able to operate the conveyor in a manner to (1) retract the product from the blade when slicing is to be interrupted to prevent the formation of nonuniform end slices, and (2) reinsert the product into the slicing position during the "dwell period" of the blade after point 23 has passed the product and before point 20 reaches the product.
  • a slicer control circuit capable of correctly positioning the product relative to the rotation of the blade is disclosed.
  • This circuit is used to drive the conveyor motor control including both the speed and direction of the motor through a digital speed control system of a conventionally available type.
  • the circuit employs a shaft encoder 50 to monitor the angular velocity of the knife motor 52.
  • This motor is controlled by a drive amplifier 54 which is manually adjustable in a manner well known in the art.
  • the drive motor and amplifier are contained within dashed lines 56 to indicate that they are conventional and form no part of the present invention.
  • the first output is a pulse representative of each degree of rotation of the blade. Thus, 360 pulses are produced per revolution of the blade. If desired, a divider may be employed to reduce this pulse frequency if less precision is satisfactory.
  • the second output from the encoder, on line 58, is a single pulse per blade revolution. This output is provided to a slice counter 60. Counter 60 contains the number of slices and can be set to provide an output upon reaching a preselected value corresponding to the required number of slices per package. Upon reaching the selected value an output is produced on line 62.
  • a scale or similar device measuring the weight of the sliced product can be employed to produce an output on line 62. In that case the output from the encoder on line 58 is not utilized. Regardless of the manner in which the last slice signal is produced on line 62 the remaining portion of the circuit is unchanged.
  • Both inputs from the shaft encoder 50 are provided to a knife position counter 66 while the output on line 56 is also provided to a frequency to analog converter 68.
  • the converter may include a bistable multivibrator, for example, RCA part No. CD4047AE to wave shape the pulses from the encoder.
  • the output from the multivibrator is provided to a simple RC network to produce the desired analog signal.
  • the converter translates the pulses representing the angular velocity of the blade to an analog voltage which, in turn, is applied to a voltage controlled oscillator 70, the output of which is connected as one input to AND gate 72.
  • the knife position counter 66 is a digital counter of the commercially available type which should have a storage capacity at least sufficient for the number of pulses produced by the shaft encoder 50 corresponding to one revolution of the blade. In the case of the present embodiment the counter should be able to count to at least 360.
  • the counter input on line 56 is utilized to increment the counter during blade rotation so that the angular position of the blade at any given instant can be determined by the value stored in the counter 66.
  • the output from the shaft encoder on line 58 is utilized to reset the counter to zero in preparation for the next slice.
  • Two outputs are obtained from the counter 66 on lines 74 and 76.
  • the output on line 74 is the "start slice" signal and is provided as one input to AND gate 78.
  • This signal is merely an output derived from the counter when it reaches a preselected value corresponding to the proper angular position of the blade for initiating operation of the conveyor to correctly position the product to begin or resume slicing. In theory the signal would be produced on line 74 as soon as point 23 on the blade had cleared the product slicing position initiating the blade dwell period. In practice, of course, it may be desirable to start the positioning process either earlier or later than point 23 on the blade. Regardless of what point is selected, it corresponds to a count in the position counter 66. The desired count is then provided on line 74.
  • the appropriate point for interrupting slicing and withdrawing the product from the blade corresponds to a numerical count in counter 66 and when that count is achieved an output is provided on line 76 as one input to AND gate 80.
  • the second input to AND gate 80 is the output on line 62 from the slice counter 60 or, alternatively, a weighing device utilized in place of counter 60.
  • the second input to the AND gate 78 is the signal on line 62 inverted by inverter 82.
  • the output of AND gate 78 is provided to the set input of a flipflop 84 while the output of AND gate 80 is provided to the reset input of flipflop 84.
  • flipflop 84 when flipflop 84 is set the control circuit is in a slice mode. When flipflop 84 is reset, the control circuit is in a retract or interrupt slicing mode.
  • Both outputs from the flipflop 84 are provided as inputs to OR gate 86 which, in turn, is connected to a one shot 88.
  • One shot 88 when triggered by OR gate 86, generates a pulse as indicated in FIG. 4 waveform 89.
  • the one shot can be reset prior to the completion of its present pulse by a reset line 90.
  • the output of the one shot is provided on line 92 as a second input to AND gate 72 via inverter 94.
  • the one shot output is also provided as one input to an AND gate 96.
  • the second input to gate 96 is from a pulse generator 98.
  • AND gates 72 and 96 are provided as inputs to OR gate 100, the output from AND gate 96 also being provided to a pulse counter 102, the output of which is connected to the reset line 90 for the one shot 88.
  • this subsystem includes a conveyor motor 106, a speed control 108, and a digital control system including a shaft encoder 110, position comparator 112, a system clock 114, an auto zero circuit 116 and a sine/cosine feedback circuit 118.
  • a shaft encoder 110 position comparator 112
  • a system clock 114 position comparator 112
  • an auto zero circuit 116 auto zero circuit 116
  • a sine/cosine feedback circuit 118 a sine/cosine feedback circuit 118.
  • the system is commercially available from sources such as Hyper-loop, Inc., of Bridgeview, Illinois. That company offers a digital control system employing velocity and position feedback to control motor speed and direction responsive to two input signals.
  • the first input signal is a direction signal provided from the circuit according to the present invention on line 120 while the second input is a velocity pulse train provided on line 122.
  • blocks 110 through 118 control the conveyor motor 106 in the desired manner.
  • a specific device manufactured by Hyper-loop, Inc., suitable for use herein is sold under the trademark HYSTEP.
  • the digital system controls the conveyor motor 106 in response to the direction signal on line 120 and the velocity pulse train on line 122.
  • the circuit according to the present invention generates these signals to achieve the desired objective of correctly positioning the product relative to the slicing blade to avoid nonuniform slices.
  • the velocity pulse train on line 122 is provided from the pulse generator 98 through AND gate 96 and OR gate 100.
  • the pulse generator 98 produces a high frequency pulse train to cause the conveyor to rapidly move the product toward or away from the slicing blade.
  • the pulse generator preferably has a frequency on the order of 33 K hertz. Of course, other frequencies may be suitable for different systems.
  • the pulse generator output is applied to the digital control system when the one shot 88 is triggered which, in turn, enables the AND gate 96. As seen in FIG. 4, the output 99 of the pulse generator is applied to the digital control system for only the period of time the one shot is enabled. This occurs each time that slicing is to be initiated or interrupted.
  • the pulse generator output is also applied to the counter 102 which is set to detect a selected number of pulses and to reset the one shot thereby disabling gate 96 and enabling gate 72. In this manner, after the product is correctly positioned at the slicing point or withdrawn therefrom, the high frequency pulses are no longer provided on line 122. Instead, the voltage pulses are provided by the voltage controlled oscillator 70 via AND gate 72 and OR gate 100.
  • the pulses 101 produced by oscillator 70 are of significantly lower frequency than those produced by pulse generator 98. In fact, the output of the oscillator 70 is a function of the rotational velocity of the blade by virtue of its input being coupled to the shaft encoder 50 via the frequency to analog converter 68.
  • the direction signal on line 120 is connected to the Q output of the flipflop 84.
  • the Q output of the flipflop is connected via line 121 as a third input to the AND gate 72 to insure that the voltage controlled oscillator produces the velocity pulse train only during the slicing sequence.
  • An important feature of the invention is the control of the conveyor speed as a function of the angular velocity of the blade. This insures that during slicing the passage of product past the blade is at a rate consistent with the blade speed to insure uniform slices of product.
  • the shaft encoder 50 would detect this fact and result in a lower pulse frequency from the voltage controlled oscillator 70. In turn, this would drive the conveyor at a slower rate.
  • the pulse generator 98 which inserts and withdraws the product is independent of knife speed to insure accurate positioning of the product.
  • the product 12 is loaded onto the conveyor 11 and the conveyor may be manually operated to position the product into the position shown in FIG. 1.
  • the slice counter 60 is reset, either manually or automatically, thereby generating a low signal on line 62. This is inverted by inverter 82 and provides a high signal to AND gate 78.
  • a high signal is produced on line 74 thereby enabling gate 78 and setting flipflop 84.
  • the start signal on line 74 is produced by the knife position counter 66 which tracks the angular velocity of the knife blade 16 by virtue of the shaft encoder 50 operatively connected to the shaft of the motor to which the knife blade is attached.
  • Setting flipflop 84 puts a low signal on the Q output providing a direction control signal on line 120 causing the conveyor to move the product towards the blade. At the same time the high Q output triggers the one shot 88 thereby disabling AND gate 72 and enabling AND gate 96.
  • gate 96 is enabled the output of the pulse generator 98 is applied to line 122 causing the digital control system to drive the conveyor rapidly forward to correctly position the product beneath the blade prior to the blade initiating a slice. Thus, when the blade finally reaches the slicing position the product will be properly located thereunder and a uniform first slice will be obtained.
  • the pulses from the generator 98 are counted in the pulse counter 102 and when the preselected count is reached, indicative of the point in time where it is necessary to discontinue the fast pulse train to prevent overshoot, an output is provided on line 90 which resets the one shot.
  • inverter 94 provides a high input to gate 72. If the flipflop 84 is in the slice mode, a second high input is provided on line 121 and thus the voltage control oscillator 70 begins producing the velocity pulse train on line 122.
  • This switching between the high frequency pulse generator 98 and the voltage controlled oscillator 70 is a significant feature of the invention. It permits synchronous operation of the blade and conveyor during slicing and a synchronous high speed insertion and withdrawal of the product when desired.
  • Resetting the flipflop reverses the polarity of the direction signal on line 120 indicating a direction away from the blade is desired.
  • the Q output also triggers one shot 88 and, as previously described, this gates the pulse generator 98 onto line 122. The product is therefore rapidly withdrawn from the blade before a nonuniform partial slice can be cut.
  • the one shot After the product is withdrawn from the slicing position the one shot resets.
  • the conveyor stops moving away from the blade since line 120, the third input to the AND gate 72, is low.
  • the conveyor remains in this stand-by position until the slice counter 60 is reset, either manually or automatically, initiating a new slicing cycle.
  • any variation in knife speed detected by the shaft encoder 50 is compensated for by reducing or increasing the output of the voltage control oscillator 70. In turn, this maintains the operation of the conveyor at the proper speed relative to the knife velocity to insure uniform slices.
